TEA1103T
Overview
The TEA1103x are fast charge ICs which are able to fast charge NiCd and NiMH batteries. The main fast charge termination for NiCd and NiMH batteries are ∆T/∆t and peak voltage detection, both of which are well proven.
- Safe and fast charging of Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries
- Pin compatible with the TEA1102x, fast charge ICs for LiIon, SLA, NiCd and NiMH batteries
- Three charge states for NiCd or NiMH; fast, top-off and trickle or voltage regulation (optional)
- Adjustable fast charge current [0.5CA to 5CA nominal (CA = Capacity Amperes)]
- DC top-off and pulsating trickle charge current (NiCd and NiMH)
- Temperature dependent ∆T/∆t battery full detection
- Automatic switch-over to accurate peak voltage detection (-1⁄4%) if no NTC is applied
- Possibility to use both ∆T/∆t and peak voltage detection as main fast charge termination
- Support of inhibit during all charging states
- Manual refresh with regulated adjustable discharge current (NiCd and NiMH)
